Help Unity Remote

Hello all,

I have tried a to create a simple scene of a image target when scanned will show a piece of geometry, In play mode from the editor the scene works good, and when exported it works well too... 

I am using unity version 201.3.14f1, vuforia 8.110 ,I have installed android studio and google usb driver,

When the phone is connect using usb cable and I hit play I see the image target and the 3d mesh, The camera is supposed to show me live steram capture right? can some one tell me how to go about this. and oh my phone is redmi note pro 6

Thanks
